This report presents the results of excavations of an Archaic campsite in southern Illinois. This was a seasonal camping place of many Archaic peoples and was especially tantalizing to archaeologists because of the unusually large number of artifacts found here. The report is illustrated with excellent photographs and line drawings.

In this ethnological treatise, former Museum Director Thorne Deuel analyzes 35 traditional cultures from around the world focusing on the universal factors that govern cultural behavior.

Psaronius, a tree fern, was the dominant plant in Late Pennsylvanian coal swamps, comprising as much as 85 to 90 percent of some coals.

Using photographs and drawings, the internal structure and ontogenetic development of various species are illustrated.

It is meant as a ready reference on the distribution and use of Midwestern wild or naturalized plants for food, medicines, beverages, tobacco substitutes, dyes, or technological purposes.
